| titleOfInvention | Method for simultaneously extracting iodine and fucoidin from salted kelp blanching wastewater |
| abstract | The invention provides a method for simultaneously extracting iodine and fucoidin from salted kelp blanching wastewater, belonging to the technical field of environment protection and chemical industry. The method particularly comprises the following steps of: (1) cooling kelp blanching wastewater; (2) degrading nitrate nitrogen and nitrite nitrogen by inherent microbes in kelp blanching wastewater; (3) adding caustic soda into denitrified kelp blanching wastewater, so that the fucoidin is basified, flocculated, and layered in a floating way, filtering, and drying to obtain a fucoidin crude product; (4) pumping the fucoidin-removed kelp blanching wastewater into an acidification tank, adding oxidant, so that iodide ions in solution can be completely oxidized into iodine, and enriching iodine by ion exchange resin; (5) dissolving iodine absorbed in the resin by NA2SO3 solution; and (6) oxidizing iodide ions in desorption solution into the iodine by KClO3 oxidant, crystallizing, separating out, centrifuging, and filtering to obtain crude iodine. According to the method, iodine and fucoidin can be extracted, and the multipurpose utilization rate can be improved, so that the resources waste and the environment pollution can be avoided. |
